Who was behind Pakistan singer's murder?

A popular singer's murder on June 18th has reignited the debate on freedom of expression and the weight of tradition in Pakistan. Ghazala Javed was known for standing up to the Taliban when they banned singing and dancing in her home province of Swat Valley. The 24-year-old had two dozen albums to her name, and millions of fans across Pakistan and Afghanistan. But it's thought she might have died following a domestic dispute rather than a revenge killing.
